Abstract

Oppfinnelsen angår en fremgangsmåte for dataoverføring, samt et radio- system som omfatter minst en abonnentterminal (200) og minst en basestasjon (100) som omfatteren antenne (140, 141) som basestasjonen sender signaler til abonnentterminalen ved hjelp av. Abonnentterminalen (200) omfatter en målean- ordning (230) som bestemmer kvaliteten av signalene som mottas av abonnent- terminalen, ved å sammenligne de mottatte signalene med minst ett terskelnivå for signalkvalitet. Når bare ett signal overskrider terskelen, sender abonnenttermi- nalen (200) til den basestasjon (100) som utsendte signalet som overskred terske- len, en kommando om å benytte, når et signal blir sendt til denne abonnenttermi- nalen, den antenne som signalet som overskred terskelen, ble sendt med, eller den senderetning som signalet som overskred terskelen, ble sendt i.The invention relates to a method of data transmission, as well as a radio system comprising at least one subscriber terminal (200) and at least one base station (100) comprising antenna (140, 141) from which the base station sends signals to the subscriber terminal by means of. The subscriber terminal (200) comprises a measuring device (230) which determines the quality of the signals received by the subscriber terminal by comparing the received signals with at least one signal quality threshold level. When only one signal exceeds the threshold, the subscriber terminal (200) sends to the base station (100) which transmitted the signal exceeding the threshold a command to use, when a signal is sent to this subscriber terminal, the antenna as the signal that exceeded the threshold was sent, or the transmitting direction in which the signal that exceeded the threshold was sent.
